prefer to set so that the stock shall be" reduced to a fine fiber, as therebyv the seeds or kernels will also be correspondingly reduced and be most eflicient as a cement. After reduction the pulp is passed on to the papermakingmachine and there run into paper or board in the usual manner.

Be it lmown-thatI, Georges-W. Downs, a a citizen oithefFUnited States; residing at Newark, in the-county senses. and State at New Jersey, haveinventedcertainnewjand useful Lnproveme ts in Baperor Board,;o which. the ,following'isa ii-n11, clear," and exact specification. Lv

My invention relates'to zen-improved" pa peror board, and beers;- its object to, make an improved paper; or board which'canibei produced quid y andf-economically, and which possesses many desirable qualities My improved paper-or board is referably made ofspenthops", ,towit, sue hops brewers and from fthe merely the center, but its valuable properties would still be; evident.

It is apparent'that o'ses thespent hops will. form a stock of'sufa stronger product be desired a proportion of stronger fiber, such as sulfite, jute,or suitable mixed papers may be added. The said spent hops, owing to the treatment which they have passed through at the breweries, are soft and quickly reduced to pulp, and I 1 have found-that they may be prepared in an hour or even less.

Old hops or damaged hops which are less raluablefor brewers use may also be used by me as well as spent hope, as they contain all necessary material for the manufacture of paper or board, and the kernel of such hops is equally well adapted to serve as a binder, but in the use of such old'or damaged hops (which are not spent) a slightly longer time is requiredin the beating engine.

By the expression seeds or kernels in substantially; their natural condition, or resinous matter in substantially its natural I condition in the claims, is meant that the seeds or kernals, and the resinous matterrespectively, have not been neutralized with an alkaline solution.

What'is claimed is:

L A paper or board containing .spent hops having the seeds or kernels minutely subdivided, but otherwise in their natural condition and uniformly distributed throughout the body of the paper or board.

2. A paper or board containing spent hop leaves and avbinder formed of hop seeds or kernels-and the resinous matter of said 'beenextracted, by reasonof the chea ness of suchmateriahand I use the) entire liody. of such-hops, not oniy the leaves, but the-seeds or kernels asfwell, and in the use of'such seeds orkernels resides an important part of my invention, as I have found that such kernels contain a very large percentage of resinous matter, wellfas an ortant percentage iof cellulose, and the "such kernels, when properly. reduced, form an adhesive mixture of the nature ofa paste together. the fibers.

The paper orboard produced by me from such spent hops is of a light porous cha'rac-, tar, quitethick for its weight, and of 'a spring'y, elastic character, thereby admirably fitting it for-use where aboard or paper stance," asa caret'lin ing, for which use it may, if'desired, e corrugated. v Inproducing-my' roved product, I' take the spent hops prefera I 1y as they come from the breweries, usually in a moist or soaked condition, in which condition they are soft hout any preliminary treatment by chemicals or machinery, them in the usual Holland beating engine, where they are reduced ineither hot or cold water, and from which they later pass through a Jordan or refining engine to Y the paper machine.- This J ordan' engine I- ca'se the saidhop-board or paper would form cient strengthto make a paper or board, if
